Hi,
I have the listed the gdalinfo listing of an erdas imagine file below
and notice that it does not have a EPSG code within it. I need this
EPSG code if I want to reproject within gdalwarp or for on the fly
projection within mapserver. Based the gdalinfo listing I searched
within the epsg file and found the following code and definition:
# WGS 84 / UTM zone 18N
<32618> +proj=utm +zone=18 +ellps=WGS84 +datum=WGS84 +units=m +no_defs <>
Does the above EPSG code of 32618 make sense for the below gdalinfo listing?
John,
Yes, EPSG:32618 is equivelent to the following definition.
